Importance of elongation and organogenesis on rhizome length of Zostera marina in an Individual-based simulation model, datasets.
This datasets contains the observations used for the parameterization and validation of an individual-based model (https://doi.org/10.5281/zenodo.3763829). This IBM was used to assess the relative importance of elongation and organogenesis rates in the rhizome length of eelgrass Zostera marina. The database includes morphometric measures of Z. marina as well as some environmental conditions from the Punta Banda estuary, in Baja California, Mexico(31°409' to 31°489' N, 116°379' to 116°409' W), in biweekly samples from the years 1999-2000 and 2018. As well as, some environmental conditions are presented. Sea surface temperature (°C): Temperature measured in situ. Sea surface temperature anomaly (°C): Data were obtained from the IRI/LDEO Climate Data Library. For the required fortnights, each day was assigned the corresponding observed value of biweekly SSTA in the database, and the mean SSTA during the ~15 days of the sampling period was calculated; this was the value used as the observed SSTA at each fortnight. Irradiance (kWm^2 fortnight). Hourly Irradiance measures (Wm^2) were obtained from the National Renewable Energy Laboratory. The irradiance in the fortnight was the sum of the hourly irradiance each hour during the fortnight. Hours of air exposition. Hourly sea level data was obtained from the Mareographic network of CICESE. The marked rhizomes were located in the higher part of the meadow, assuming the measures were made at a depth of maximum 50 cm, the hours of exposure to air were the number of hours that the sea level was equal or lower than this level.
